Apple CEO Tim Cook Keynote at WWDC June 2013 Conference Transcript

And now that I have that tag, I can also assign tags by just dragging things in to the Tagger and the Finder. So different assets from my website, just drag them in and they’re tagged like that. And tags are great for searching.

So if I start typing, let’s say, Important, it can find all documents that are important. Let’s go to All My Files, we’ll find all documents, they’re both important and that are in review. Just like that, I found exactly what I’m looking for with tags.

Next, let’s take a look at Multiple Displays. I’m going to open up some other kind of windows that I’m often working with. We’ll open iPhoto here, may be a keynote presentation. And I actually have a second display connected to this MacBook Pro. Let’s show that up there on display now. Of course with multiple displays, I can just move windows across displays like you’d expect.

But now, I can get up at my Menu bar in the second display. If I go down to the bottom, I can summon the dock just like that. If I want to open an app on the second display, I can just open that on the dock here and here is iTunes. Take this app full screen just like that. And as I swipe spaces, just right back there.

Just on that display, let’s take a keynote full screen as well. I’m going to go back to my first display here. Let’s even take iPhoto full screen. So now, I have different full screen apps on my different displays. This is actually really fantastic way to work. Go in here into Favorite Travels and I can now drag assets across my full screen apps like that, super cool.

And, Mission Control has just been super charged for multiple displays. So, I’m going to go now into Mission Control and we see my different full screen spaces and desktops across applications. I can drag a window from one display to another. I can also go and drag a full screen app right across displays, bring Preview open, and now I have that full screen on this display as well.

Finally, I actually have an Apple TV around here. Let’s bring that into place. So here’s my Apple TV. Now, this is pretty over the top. So I can actually go here into AirPlay. I’m going to connect to this Apple TV. So now, it’s a full power display as well.

You can see I have my Menu bar and my dock. I can go over here and get my dock here. And, I can go into Mission Control, even, and I can go get a window across that other display.

We’ll just drag Keynote over here, right on to my Apple TV, and open it up. There it is, full displays in Mavericks.

Next, I’d like to talk about some advanced technologies in Mavericks. You know, our power users are increasingly doing their work on the go. They want great responsiveness but they also want great battery life.

And in Mavericks, we’ve introduced a whole host of technologies to address that challenge. Things like Compressed Memory that make sure you have memory available very quickly when apps demand it. Technologies like App Nap that actually makes sure we’re directing power only to those applications where you’re really benefiting from it. System-wide Core Animation Accelerated Scrolling and OpenGL 4 for super responsive graphics.

And, a topic I want to go into in a bit more detail now, Timer Coalescing. So you know, when you look at battery life on your computer, the real factor that software has the most influence over is CPU activity and its draw on power. And if you look at what your system is doing at any given time, what you’ll see as you look under the hood is not a smooth line, but actually hundreds of interrupts occurring per second where the system is going from a power-efficient sleep state up to a state of high power use and back down. And all of those transitions actually consume a lot of power.

Well in Mavericks, we intelligently align all of that work, reducing those numbers of transitions. This, in combination with technologies like App Nap and other power optimizations, reduce CPU utilization activity for these kinds of scenarios up to 72%. It’s pretty awesome.

Next, let’s talk about Compressed Memory. Nothing affects the performance of your Mac, the responsiveness more of a Mac, that’s under load than its ability to provide free memory to an app. Now, typically, when you look at your app runtime, all your memory is inactive. In fact, a subset of your memory is actively being used and others is memory we have to keep around but isn’t being used by the app.

Well, now if you open a document, your system is going to need to get free memory and it does that in the past by writing those inactive bits of memory out to disk, and that’s a slow process. Now, with Compressed Memory, we’re able to rapidly compress the inactive memory making free space available almost instantaneously to the application. This can have great effects on responsiveness of systems under load. You see, 1.4X kinds of improvements, even on fast SSD systems for activities like opening new documents or reactivate an application, and up to 1.5X improvement for waking a system from standby, these are just two of many improvements to power and performance in Mavericks.

Next, let’s talk about Safari. In the last decade of life, Safari is focused not just on providing the easiest to use and most elegant browsing experience, but also the most innovative. These are the kinds of innovations that Safari has brought, private browsing, blocking of third party cookies for privacy, making the web easier to read with features like Reading List, and the HTML5 audio and video tag, all Safari-firsts. And the engine in Safari, WebKit, is used by over 1.5 billion devices.
